While its pretty obvious that the naughty gym goer stuck his penis into the weight's orifice, the Fire Department won't explicitly say.

However, people are totally convinced he did! Social media users wrote (translated from German):

"Did he stick his dick in the hole? If so, how do you come up with shit like that? Was that supposed to be an exercise for more stamina in bed?"

"Whoa dude seriously? They only fit your index finger, seriously I work with those weights every day. Sorry but he must have had a pretty small one if he fit in there."

"When his grandkids ask him one day: 'Grandpa, what was your biggest accomplishment in life?' He can say: 'One time I went viral on the internet…' And his grandkids will say: 'What? How?' And he'll go: 'Well um there was that one time I went to the gym…'"
